This invention is shown embodied in .a cash register of the type shown and. de scribed in the patent to Frederick Fuller No. 1,394,256. In machines of this type it is usually customaryto provide three banks of control keys. Such machines can also be equipped with any number of cash drawers from one tonine, one drawerbe ng provided for each clerk using the machine. In the previous machines ofjthis type the release ofthe caslrdrawers was controlled by a single bank of keys; butthis. machine has been designed so that each cash drawer m y be r as by i e -ea a th three control banks. It'will be evident that this drawer control meehanisin; can be con- 7 strueted to operate in connection. with two,

showiiig' and the description thereof in this application therefore will be as much simplified as possible. Eachbank containsnin'e keys (Fig. 1), which are slidably moilnted in a lrey frame 31, supported'at its upper and lower ends rods 32 and 33. These keys are adapted to be held in their deore'ssedposition during the operation of the macl rine, and restored to their undepressed positionjat the end of such operation in a manner whiclris Very Well known, and the 1clescriptiol'i of which is accordingly omitted ere.

The differential mechanism forth'e release banks is old and well "known ancl only a very brief description thereof will be included in this application. latch'membe'r 34 pivotally supported by an arm 35 and a bell 'crank lever 36, which are in turn carried by a differentially movable member 37. This' rnembe'r is pivoted on a stud 38 and i s driven by an invariably I'r'roved segment 3 9, alsopiv'oted on the stud 38'. The segment 39, as is well known, is given its invariable movement by means of a link EO, a Y-shaped member ll and a pair of earns 42 and 43, which are taston a shaft shaft is the main drive shaft of the machine and receives one complete rotation on every operation thereof, "thereby causing the Y- shaped r'n'e'mber'tl to rock firstcl'oclgw'ise'a nd then dounter-clockwise" about itsp'iyiot. On the clockwise moyement of the Y-shaped -memberh, the segment 39 and the dilferentially movable member 37 will be rocked clockwise until the" forward. end of the bell crank leve'r 36 comes into contactwith' the inner end of whichever oneof the keys 30 has'been depressed; Whe'n'this' dcciiis, the latch member 34] will be disconnected from a shoulder on the invariably moved segment 39 and the differentially movable member 37 will be stop ed in a position corresponding to the key epressed. If no key in a bank has been depressed, the latch will be broken or moved into unlatching position by means of a zero stop pawl 45, the operation of which is very well known and which is shown in the copending application of B. M. Shipley No. 576,924, filed July 20, 1922. The bell crank lever 36 is connected by a slot and pin connection to a member, shown broken away, also pivoted on the stud 38 which is in the same plane as the zero stop pawl 45.

When the invariably moved segment 39 is rocked counter-clockwise to its normal position, a surface 46 thereof will strike a pin 47 on the differentially movable member 37 and return this member to its normal position. Pivoted to the member 37 isa beam 48, which at its opposite end is bifurcated and cooperates with a pin 49 carried by a link 50. The link 50 is pivoted at. its upper end to a segment 51, which is adapted to .position'both the corresponding indicators and the desired totalizer in a manner which is described in the above referred to. atent. At its lower end, the link is pivote to an arm 52 loose on a rod 53 supported by the machine side frames. Secured to the arm 52 is a segment gear 54, the teeth of which mesh with teeth formed on the forward end of a rack 55. The forward end of this rack is slidably su ported in a cross member 56, also supporte by the machine frames. The rear end of the rack carries teeth 57 which mesh with a gear 58 loose on a shaft 59 (Figs. 1, 2 and 3). This shaft is rotatably mounted in two brackets 60 and 61 which rest on the base of the machine. The Y-shaped member 41 carries a roller 62 which, when the Y- shaped member receives its clockwise movement, will contact with the lower edge of the beam 48 and position this beam and the link 50 differentially, in accordance with the position in which the latch of the difl'erentialmechanism was broken under control of the depressed key. The differential movement of the link 50 will be transmitted through the arm 52, segment 54 and rack 55 to the gear 58, which is appropriate to the particular bank operated, and this gear will therefore be'rotated in a clockwise direction a distance corresponding to the key depressed. Each of the gears 58 is connected by means of a hub 63 (Fig. 2) to an arm 64 which'lies in the same plane as a pin 65 carried by an arm 66 13 fast on the shaft 59. 7 It is, therefore, ap-

aarent that when the gear 58 correspondlng to the key bank operated is given its clockwise movement, the shaft 59 will be carried in a clockwise directionto an extent cpxresponding to the key depressed, but the arms 64 for the other banks of control keys The drawer mechanism of the present machine is of conventional design in most respects, and it is not believed that a specific description of the mechanism is essential to an understanding of the invention.

As shown in this application, the machine is provided With nine cash drawers Fig. 3 showing the top and bottom drawers only. Each of the cash drawers 77 isslidably mounted in an opening in the base of the machine. On the back of each of the drawers a bracket 78 is bolted, to which is pivoted a drawer latch 79 which has a shoulder 80 engaging a hardened plate laid in a bar 81 extending laterally across the rear of the machine, and supported by vertically extending members 82. There is one of these bars for each drawer. The latch 79 is held in its latching position by means of a spring 83 stretched between a projection on the latch and a pin on the bracket 78. \Vhen the drawer 1S unlatched in a manner which will be presently described, it is moved forwardly out of the drawer cabinet under the influence of two springs 84, the construction and function of which are old and well known.

The cash drawer to'be released is selected by the key depressed in any of the three control banks. The machine is so constructed that only one key may be depressed in the three banks. No matter in which bank the depressed key may be, the shaft 59 (Figs. 2 and. 3) will be rotated difierentially in accordance therewith in the manner previously described. Fast on this shaft is a spiral gear 85, which meshes. with a spiral pinion 86 (Fig. 4) fast on a short vertical shaft 87. At its lower end. the shaft 87 carries a member 88, the front and back of which are flattened, and which is adapted'to'be inserted into a c0rresp0nding opening in a cylindrical member 89 carried on the up er end of a shaft 90 as shown more clear y in Fig. 5. It can be seen that due to the construction of these parts a rotary movement of the spiral pinion 86 will be transferred to the shaft 90, and also a vertical movement'of'the shaft 90 and the member 89 can be effected without raising the spiral'pinion 86. At its lower end the shaft 90 rests on a projecting lug 91 extendin upwardly from the base of the drawer ca inet. A torsion spring 94 is wound about the shaft 90, and is anchored at one end to a collar 92 which is secured to the shaft, and at its other end to a portion 93 of the frame. This spring constantly tends to rotate the shaft 90- in a counter-clockwise direction, as viewedin Fig. 4, in order, through the spiral gear 85 and shaft 59, to

keep the pins 65 on arms 6'6 constantly in engagement with the arms 6 1. It can be seen from the above description that when the shaft is rotated differentially oy the differential mechanism appropriate to one of the three control banks of keys, the shaft 90 will. also be rotated differentially to a like extent against the tension of the spring; D-l.

Fast on the shaft 90 are a plurality of or lingers, 95, which differentially and spirally disposed about the periphery of the shaft 9-0, one opposite each of the cash drawers. Thus, if the 9 key in any one of the three banks is depressed, and through the differential mechanism the shaft 90 is rotated to its 9 position, the lug 95 approg lriate to the lower. or ninth, cash drawer will be moved into position to cooperate with this drawer. Pivotally mounted on the frame 81 is alever 100, the movement of which is limited by a pin 101 which projects through an opening in said lever. The lever extends laterally of the machine and norn'ially lies just above the latching arm 79 for each cash (JEI'WBE. It is evident that when the left hand end (Fig. 3) of the lever 100 is raised, the right hand end will be lowered and therefore the latch arm 79 will be pushed downwardly far enough to disengage its shoulder 80 from the plate in bar 81 and thereby permit the springs 8": to force the drawer forwardly to its open position. The means for rocking, the lever 100 will now be described. It can be seen in Fig. t that the member 89, which is carried on the upper end of the shaft 90, has a horizontally extending channel 102 out therein. Fast on a shaft 103 is a ti -shaped member 10% which carries two pins 105 projecting into the channel 102. Fast on the shaft 103 is an arm 106, the free end of which rests on the left hand and of a lever 107 pivoted on a stud 108 of the frame. The opposite end of the lever 10"? carries a roller 109, which cooperates with the periphery of a cam 110 fast on a shaft 111. oi've shaft, shown in the above mentioned fl dent and there numbered 2 12, Figs. 50 and 51, and receives a complete clockwise rotation 1) upon every operation of the machine. When this operation takes This shaft is the main printer place, the earn 110 will roclr the lever 107 clockwise, which will in turn rock the arm 106, shaft 103 and U-shaped member 104i also clockwise, thereby raising the member 89 and shaft 90 upwardly, the cam 110 will then permit the parts to return to their normal positions, as shown in Fig. 1, Upon the upward, movement of the shaft 90 the lug 95, which had previously been posi tioned under control of the keys, will cooperate with its appropriate lever 100 and rock this lever, thereby rocking the latch arm '79 and releasing the particular drawer selected.

While the form of mechanism herein shown and described is admirably adapted 1 to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodimentherein disclosed, for it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow;

lVhat is claimed is:

1. In a cash register, the combination of a plurality of cash drawers, a finger shaft the position of which determines which of said drawers will be released, a transverse shaft adapted to drive said finger shaft, a plurality of arms fast on said shaft, studs n'ojecting laterally from said arms, a plurality of members loose on said shaft one for each of said arms, gears secured to said members, and racks one for each of said gears for operating the finger shaft to determine which of said drawers is to be released.

2. In a drawer selecting; mechanism, the combination of a shaft for controlling the selection of drawers, a plurality of arms fast thereon, and means for driving said. arms to different extents in order to posi tion said shaft.

In a. drawer selecting mechanism, the combination of a shaft for controlling the selection of drawers. a plurality of arms fast thereon, pins projecting laterally from said arms, and means cooperating with said pins for driving said arms and positioning said shaft to select the drawer to be operated.
